Hi, I’m Bonnie Kaye. There are beginning, intermediate, and advanced ways to do just about every exercise. Here are some good, better, and best bets to work your abs and glutes.
Sot Stacy: 
Well if you keep doing the same exercises the same way, you’re gonna keep getting the same results. So by mixing it up a little bit, you’re going to get your muscles to work a little bit differently, you’ll jump start them and you’ll get better results. 
Bk: Okay, and so you start out as a beginner, you might want to do an exercise one way, but then you can always make it a more moderate intensity then more advanced.
Stacy: You just keep progressing, and then if you’re having a bad day, you can drop back to the exercised before it.

Let’s start with the glutes. First, the basic squat, legs apart shoulder width, back aligned, knees about the ankles.

An intermediate variation would be to add a side ways squatting movement. The momentum pushes you into a deeper squat, and you also get your inner and outer thigh muscles a little more.

And an advanced glute exercise—plyometrics. Clasp your hands, and jump up, reaching upward as you jump up, then squatting deep when you land. This is not a good idea if you have knee or back problems.

Now for your obliques, or waist area. A basic exercise would be a torso twist, lying down with your hands relaxed behind your head.

The next level would be to add a punch. This is a bit tougher, and helps break up the monotony.

And finally, a very unique and advanced exercise—lie on your stomach, elbows by your chest, palms up, then lift up onto your toes. Next, drop one knee under and across your body, alternating sides as you twist your obliques from side to side.
